Overview
Orion Van Gear Flanged Button Head Socket Screws combine corrosion-resistant 316 stainless steel construction with an integrated flange and compact button head profile. The flange creates a broader bearing surface beneath the screw head, helping distribute clamping force without requiring a separate washer in applications where the flange provides the needed bearing area.
Each screw uses standard 1/4-20 UNC machine threads and is fully threaded for flexible fastening across fabrication, T-slot assemblies, automotive projects, RV builds, outdoor installations, and general hardware applications. A 5/32 in internal hex socket allows installation using a common Allen key, hex bit, or driver.
The screws feature a black oxidation finish over the 316 stainless steel construction for a dark, low-profile appearance. Five length options are available from 3/8 in through 1 in. Each resealable Orion Van Gear package contains 25 screws in the selected length plus 1 matching spare, for 26 screws total.
